It is an object of this invention to provide an improved metal roofingfor-med of a :fiat metal sheet so related to an adjacent sheet and "tothe roof to which it is attached that.theroofing-wll be securelyfastened to the structure and the an improved metal roofing of thekindto-be more particularly described hereinafter in Which the adjacentroofing sections maybe sealingly secured together, and having means torsecuring the con-' nected sections to the supporting or roof structurewhereby the entire roofing will be held against removal by wind orstorms or thelike.

Withthe above and other objects in view, my inventon consists in thearrangement, combination and details of construction disclosed in thedrawngs and specificaton,and then moreparticularly pointed out in theappended claims.

In the drawings,

Figure 1 is a top plan view partly broken away, of an improved metalroofing.constructed according to an embodiment of this'inventon,

Figure 2 is a horizontal section taken on the line 22 of Figure 1,

Figure 3 is a vertical .section.taken;on the line 33 of Figure 2,

*Figure4 is.a vertical sectioh*taken on the iline 44 of Figure 2, and

Figure 5 is a horizontal section*taken on the line 5-5 of Figure 2.

Referring to the W drawings, the numeral ID designates generally a flatsheet of metal forming a section of a metal roofing which is adapted tobe secured to the rafters ll or supporting structure so that the roofingwill be securely attached to the structure and held against inadvertentgremoval by wind or storms or the like.

The flat section o is formed of a central flat body portion 2 having aperipheral flange 14 formed along the edge thereof. The flange I4extends vertically upwardly from the panel or central section I2 atright angles thereto.

The flange l extends along one longitudinal edge of the central panel l2and is adapted for engagement with a fiange I5 of an adjacent panel [6or roofing section l0a.

The fiange 15 is formed of a vertic ally extend- 2 ing arm flperpendicular to the base HS having a rever'ted arm IB extendingdownwardly from the upper end thereof. The-flange M of the panel l2 isadapted to engage between the arms ll and i'80f theflangei5*on theadjacent section Hla.

The panels I2 and 16 may be secured to the rafters l l by bolts 'l9Which engage through the body of the panels and into the rafters.- Forsealing the engagementof the flanges -l4-and 5, I haveprovded a spring-pressed meta1clamp2. The metal Clamp "2B is ormed'of a clamping member2| which is adapted to engage one of the fianges as15 along the-lengththereof.

The clampingmember 21 is formed With an upper fiatend 22 "which isadapted to overlie in abutting relation the upper end of the arm H. Thelower end of the clamping member 2l is bowecl outwardly as indicated bythe numeral 25 so thatthe'lowerend of themember 2'I is resilient1ybiased toward the fiange l5 at the lower edgethereof.

A horizontal arm 25 'is fixed .to or formed on the upperend of theclampingmember2tooverlie the upper edge of the fianges "'l4l :and 15. A

similar clamping member 26 is provided for abutting engagement along thelength of the fiange M. The clampingmember 25 is formed of a flat uppersection 21 extending.along the length of the fianges substantallyparallel thereto and formed with a lowerzend 2'! arcuate inconfiguration opposite to the arcuate lower end 24for clampingthefianges I' l and l'5 between the lower ends thereo. l

The upper edge of the clamping member26 is adapted to underlie thehorizontal member 25 of the clamping member 20. The horizontal arm 2'5provides a suitable seal"between the clamping members20 and 26*toexclude rain or other moisture from between the fianges l4 and l5.

For securing the connection of the ad3acent roofing sections lll andllla together, an elongated bolt 29 is provided. The bolt 29 is formedwith a head 30 on the upper end thereof and is adapted to engage betweenthe flanges I4 and [5 and between the clamping members 20 and '26.

For sealing the engagement of the head 30 of the bolt 29 with the upperedge of the fianges, there is provided a U-shaped cap 3L The bight 32 ofthe cap 3| is adapted to overlie the arm 25 of the clamping member 20and the arms 33 which extend downwardly from the bight 32 abuttinglyengage the parallel side porti0ns 2| and 21 of the clamping members.

In the use of the bolt 29 for attaching the ro0fing sections to a rafterl l, rovision in the flanges need not be made for the bolt as theengagement of the bolt therebetween will force the fianges outwardly toa suitable contour as indicated in Figure to permit the engagement ofthe bolt therebetween.

In Fig. 4 I have shown a means for attaching the entire assembly to therafter l l. An attaching strip 40 is provided for engagement with bothof the fianges I4 and l5'. The attaching member 40 is formed of anelongated lengthof flat narrow material forming a lower horizontal arm4| for attachment to the rafter ll.

An upper or vertically extending arm 42 is formed at one end of the arm4| and is adapted to be disposed between the fianges l4 and 5. The

4 and the inner surface of the depending arm l8 on the flange l5. Thevertical arm 42 is again reverted at the lower end of the arm 44 toprovide a vertically extending arm 45 outwardly of the arm l8.

sheets longitudinally thereof, a reverted vertical fiange on the otherof said sheets, said first fiange engaging between the reverted portionsof said latter flange, a pair of resilient clamping members about saidengaged fianges along the length thereof and means engageable throughsaid 7 fianges and said clamping members securing said sides thereof, ahorizontal flange on one of said clamping members overlying the upperedge of said inter-engaged fianges and the upper end of the otherclamping member for sealing said fianges at their upper edges, and meanssecuring said clamping members to said inter-engaging The arm followsthe contour of the arm 8 upwardly and.is bent over the upper end of theflange 5 to provide a downwardly extending arm 45 overlying theouteredge of the vertical portion ll. The attaching member 4a maybedisposed at suitable spaced apart positions along the length of thefianges l4 and l5 for attaching them to the rafters H, and is normallycontained between the clamping members 28 and28.

A horizontal bolt 47 is provided for engagemeht through the clampingmembers, the attaching member 4, and the fianges of the adjacent roofingsections for securing them together. resiliencyof the clamping members 2and 26 is determined by the tension on the bolt 4l efiected by the nut48 threadably engaged thereon.

I do not mean to confine myself to the exact details of constructionherein disclosed but claim all Variations falling within the purview ofthe appended claims.

Having thus described my invention, what I claim is: 7

1. A metal roofing comprising an elongated flat sheet of metal, avertical flange on one longtudinal edge of said sheet, a revertedvertical flange on the opposite longitudinal edge of saidsheet,saidfirst flange slidably engagng,within the reverted verticalfiange of an adjacent sheet, a pair of resilient bowed clamping membersengaging about said engaged fianges and means securing said clampingmembers to said engaged fianges. 7

2. In a metal roofing a pair of elongated flat metal sheets, a verticalflange on one of said The fianges.

4. A metal roofing comprising a pair of flat v metal sheets,inter-engaging vertical fianges on the adjacent longitudinal edges ofsaid sheets, a pair of opposed resilient clamping members disr' posedalong the length of said fianges on opposite sides thereof, a horizontalflange on one of said clamping members 0Verlying the upper edge of saidnter-engaged fianges and the upper end of the other clamping member forsealing the said fianges at their upper edges, means engaging about saidclamping members and extending downwardly between Said fianges forsecuring said sheets to a roof, and means securing said clamping membersto said inter-engaging fianges.

5. In a metal roofing having a pair of flat metal sheets includingmarginal vertical fianges, a clamping means securing said sheetstogether along a marginal edge comprising a pair of clamping membersengageable on opposite sides of adjacent fianges, each of said membersincluding a lower outwardly bowed resilient clamping jaw, an attachingplate connected to each of said jaws, a horizontal fiange on one of saidattaching plates overlyihg said adjacent fianges and means extendingthrough said plates and said adjacent fianges for clamping said fiangesbetween said jaws.
